Thanks Google for this information. We have just launched this new upgraded forum, and some fine-tuning has meant we've needed to restart the website a number of times recently, especially yesterday. That unfortunately means everyone gets 'dumped'. Hopefully that won't be necessary too often. Our apologies for the inconvenience.

There is also a standard 20-minute session expiry for inactive users - so you will lose your logged-in status after that period of inactivity. If you are getting booted whilst active, and this continues to occur, we'd like to know, as it's something we'd need to investigate.
